Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The DSC557-054444KI1T is a crystal-less, quad output PCI Express clock generator that is compliant with Gen1, Gen2, Gen3 and Gen4 specifications. The clock generator uses proven silicon MEMS technology to provide a 100MHz differential output clock with excellent jitter and stability over a wide supply voltage and temperature range. By eliminating external quartz crystals, the DSC557-054444KI1T greatly improves reliability and accelerates product development while meeting the stringent clock performance standards of a wide variety of communications, storage, and networking applications.The DSC557-054444KI1T features an output enable/disable function that allows the output to be disabled when OE is low. The device is available in a 20-lead VQFN package. In addition to the default HCSL output format, other LVDS and LVCMOS output formats are available.
